Specific Heat: Understanding the Key to Thermal Energy
Specific heat, also known as heat capacity per unit mass, is defined as the amount of heat energy required to raise the temperature of one unit mass of a substance by one degree Celsius (or one Kelvin). It is denoted by the symbol ''c'' and is measured in units of joules per gram per degree Celsius (J/g°C) or joules per gram per Kelvin (J/gK).
Specific Heat
Heat Capacity: This is the amount of heat needed to raise the temperature of an object by one degree Celsius. It''s similar to specific heat but doesn''t take into account mass. Calorimetry : This is the science or act of measuring changes in state variables of a body for deriving the heat transfer associated with changes of its state due, e.g., chemical reactions.
Lithium
The lithium atom is the smallest of the metal atoms in the periodic table. It is the lightest and most reactive of the alkali metals, it floats on water but strongly reacts with water yielding lithium hydroxide and hydrogen gas. Lithium is a soft silver-grey metal, yet when combined with metals such as magnesium, it forms a very strong alloy.
Specific Heat
Main Idea. The Specific Heat Capacity of a substance, also known as the Specific Heat, is defined as the amount of energy required to raise the temperature of one gram of the substance by one degree Celsius. Specific Heat Capacity is important, as it can determine the thermal interaction a material has with other materials.
Specific Heat Capacity Definition
In SI units, specific heat capacity (symbol: c) is the amount of heat in joules required to raise 1 gram of a substance 1 Kelvin . It may also be expressed as J/kg·K. Specific heat capacity may be reported in the units of calories per gram degree Celsius, too. Related values are molar heat capacity, expressed in J/mol·K, and volumetric heat ...
